Geometry please help

Answer 1

b. 46°

Explanation:

In a circle, measure of minor arc is equal to the measure of its corresponding central angle.

`\therefore m\overset{\frown} {BD} = m\angle BAD = 148°\\</p><p> \because m\overset{\frown} {BD}= m\overset{\frown} {BC}+ m\overset{\frown} {CD}\\</p><p></p><p> \therefore 148° = 102° + m\overset{\frown} {CD}\\</p><p></p><p> \therefore m\overset{\frown} {CD}= 148° - 102°\\</p><p>\huge\purple {\boxed {\therefore m\overset{\frown} {CD}= 46°}} \\`
